时钟

我正在参加「码上掘金挑战赛」详情请看：码上掘金挑战赛来了！

源码：

1.html文件，引入css和js文件

主要是定义outer-clock-face和inner-clock-face两个元素

outer-clock-face元素用于定义时钟刻度：

<div class="clock">
  <div class="outer-clock-face">
    <div class="marking marking-one"></div>
    <div class="marking marking-two"></div>
    <div class="marking marking-three"></div>
    <div class="marking marking-four"></div>
  </div>

inner-clock-face元素用于定义小时、分钟、秒钟三个指针：

<div class="inner-clock-face">
    <div class="hand hour-hand"></div>
    <div class="hand min-hand"></div>
    <div class="hand second-hand"></div>
  </div>
</div>

2.css文件

css文件太长，就不放源码了、 zconst secondHand = document.querySelector('.second-hand'); const minsHand = document.querySelector('.min-hand'); const hourHand = document.querySelector('.hour-hand');

function setDate() { const now = new Date();

const seconds = now.getSeconds(); const secondsDegrees = ((seconds / 60) * 360) + 90; secondHand.style.transform = rotate(${secondsDegrees}deg);

const mins = now.getMinutes(); const minsDegrees = ((mins / 60) * 360) + ((seconds/60)*6) + 90; minsHand.style.transform = rotate(${minsDegrees}deg);

const hour = now.getHours(); const hourDegrees = ((hour / 12) * 360) + ((mins/60)*30) + 90; hourHand.style.transform = rotate(${hourDegrees}deg); }

setInterval(setDate, 1000);

setDate();
